Don't repost the exact same stuff on every site thats not good either. You can re-purpose content, Into kindle books etc.

• I post on Steemit progression photos of my art, I make money,
  -I use that art for coloring books, I make money.
  I reuse that same art for
• T shirt designs, And other uses. I make money off that too.
  -Once I stop selling a lot of coloring books, I can then take those images, and publish them as stock photo vector art, Again I make money.

Here's another example.

• I write a blog post about "nutrition". I make money.
• I eventually write a kindle book about nutrition, I make money.
• I turn that kindle book into paperback, I make money.
• I take that blog post, And turn in into a nutrition video, I make money monetizing with ads.
• I take that blog post, and add affiliate links to products I feel relate to the product, I make money when people click my link and purchase products.
